Eating more whole fruits was significantly associated with a lower risk of type 2 diabetes according to a new study led by Harvard School of public health researchers.Also this study reveals that greater consumption of fruit juices was associated with a higher risk of type 2 diabetes.
According to assistant professor and senior author Qi sun in the Department of Nutrition While fruits are recommended as a measure for diabetes prevention, previous studies have found mixed results for total fruit consumption.This findings provide novel evidence suggesting that certain fruits particularly blueberries, grapes, and apples may be especially beneficial for lowering diabetes risk.
The researchers examined the data gathered from 3 long-running studies .They looked at the overall fruit consumption as well as individual fruits consumption grapes or raisins; peaches, plums, or apricots; prunes; bananas; cantaloupe; apples or pears; oranges; grapefruit; strawberries; and blueberries. They also looked at consumption of apple, orange, grapefruit, and “other” fruit juices.Researchers found that People who ate at least two servings each week of certain whole fruits — particularly blueberries, grapes, and apples — reduced their risk for type 2 diabetes by as much as 23 percent in comparison to those who ate less than one serving per month.Also those people who consumed one or more fruit juice per day increased their risk of developing type 2 Diabetes.They also found that swapping three servings of juice per week for whole fruits would result in reduction of diabetes risk
Determining a fruit’s association with type 2 diabetes risk is not completely revealed with this study.However, the high glycemic index of fruit juice — which passes through the digestive system more rapidly than fiber-rich fruit — may explain the positive link between juice consumption and increased diabetes risk.But more research is necessary to determine which components in the fruits influence the diabetes risk.
